'Nasty' storm, tornadoes, then maybe snow in the midstate

(York) -- York County could again experience "severe weather" on Wednesday as a thunderstorm possibly capable of producing tornadoes and hail moves through the area.

Temperatures are expected to climb to a near-record high in the mid-70s ahead of the storm, according to Accuweather.com.

And, later this week, York County could see snow.

Accuweather predicts Wednesday morning showers will become heavy thunderstorms with downpours and damaging winds by the mid to late afternoon. Thunderstorms could be "on the nasty side," Accuweather meteorologist Tom Kines said. And tornadoes and hail are "certainly possible."

On Saturday, York County experienced storms that tore siding off homes, ripped off roofs, toppled trees and sent concerned residents to find cover in basements. The National Weather Service confirmed Monday that a tornado with an estimated wind speed of 90 mph touched down roughly half a mile southeast of Hallam Borough on Saturday afternoon. No injuries or fatalities were reported.

"Severe weather this time of year is not a common occurrence," Kines said. "To have it twice in the matter of a week is highly unusual."

Storms like these are caused by strong cold fronts coming through areas of warm temperatures, he said. While not brutally cold, York County will see temperatures in the 40s on Thursday -- a 30-degree temperature difference from the 75-degree high the day before.

"Typically, when you have two different air masses colliding -- one being cold and one being warm -- there's usually trouble," Kines said. "We're going to see that trouble again (Wednesday)."

Another weather system could bring snow through the area late Thursday night into Friday morning, he said.

Snowy conditions are not out of the question for the Friday morning commute, Kines said. But with temperatures reaching the mid-70s on Wednesday, the ground would have to cool down quite a bit to support accumulation.

"Worst case scenario -- there might be a couple inches," Kines said. "That wouldn't totally surprise me."

Looking ahead, Kines said temperatures will once again spike upward Sunday into Monday and Tuesday.

"We'll probably see a day Monday or Tuesday where temperatures again can get up into the 60s, maybe even the 70s again," he said. "It's kind of a roller coaster ride in the temperature department."
